Foreground Simulation Suite Plus for the 21 cm Reionization Signal Detection =============================================================

The Fg21Sim+ is a simulation suite in the radio domain aiming to offer a high resolution, high fidelity modeling of the various foregrounds for the 21 cm signal detection. This is the next-gen version of our fg21sim low frequency radio simulator. We build the Fg21Sim+ to generate a full sky simulation map for radio facilities like BINGO, MWA, and SKA.

Key Features --------* Supported foreground components:

• galactic/synchrotron: Galactic synchrotron emission (Note: Only the polarized part is considered.)
• galactic/freefree: Galactic free-free emission (Note: Update Need to update the newest version to reflect Lian et al. 2020 papers.)
• galactic/snr: Emission from Galactic supernovae remnants (SNRs) (Note: Need to check the reference and get an update.)
• extragalactic/discretesource: Emission from extragalactic discrete radio sources via AGN actvities and star formation (Note: Update Currently, Chenxi, Yongkai, and Zhenghao are working on this.)
• extragalactic/minihalo: Emission from extragalactic galaxy clusters with a miniture size (Note: Need an update.)
• extragalactic/relic: Emission from extragalactic galaxy clusters via shock reacceleration (Note: Update Currently, Yongkai is working on this.)
• extragalactic/halo: Emission from extragalactic galaxy clusters via turbulent reacceleration (Note: Update For now, only giant radio halos are considered, the modeling of which is elaborated in our paper: 2019, ApJ, 879, 104; ADS:2019ApJ...879..104L; arXiv:1905.05399)

• Full sky simulation for all components
• High-resolution, high-fedility, and high dynamic range imaging
• Instrumental effects for BINGO, MWA, and SKA with easy access API
• Diffrent level of products for various scientific usage
• Command line utilities
